[Copilot] buffer not 'buflisted' in vimagit buffer

[CheesyChocolate]

Description

I use jreybert/vimagit. I can't manage to start and attach the copilot to magit buffer.

here is my copilot config

return {
	"zbirenbaum/copilot.lua",
	config = function()
		require("copilot").setup {
			suggestion = {
				auto_trigger = true,
				keymap = {
					accept = "<C-b>",
				},
			},
			filetypes = {
				["*"] = true,
			},
		}
	end
}

here is all of my nvim config

steps to reproduce

method 1

1. invoke vimagit by nvim -c MagitOnly
2. no copilot, checking the status gives the following

:Copilot

[Copilot] Not Started

:Copilot attach

[Copilot] buffer not 'buflisted'
[Copilot] to force attach, run ':Copilot! attach'

force attaching the copilot brings it online and it works.

method 2

1. inside an existing neovim buffer that has Copilot online, open a new vimagit buffer with :Magit
2. copilot not attached, checking the status

:Copilot

[Copilot] Online
[Copilot] Disabled (buffer not 'buflisted')

Question

My real question is how to connect the copilot to a buffer that is not bufflisted. (I mean automatically)
do I need to make an autocmd?

I'm aware the correct set of action would be to do :set buflisted then :Copilot attach. but I'm
curious for a method to just attach the Copilot to any buffer.
